Influence of coagulation concentration on properties of regenerated kenaf core membranes produced in NaOH/urea aqueous solution

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Cellulose was extracted from kenaf core pulp by a series of bleaching processes and subsequently dissolved using an alkaline NaOH/urea solvent at low temperature. The produced cellulose solution was coagulated with H2SO4 at concentration from 5 to 12 wt% to produce a series of regenerated cellulose (RC) membranes. The surface morphology, structure and physical properties of the membranes were measured with variable pressure scanning electron microscope (VPSEM), X-ray diffraction (XRD), UV-vis spectrophotometer and tensile testing. The results from VPSEM revealed that the pore size of the membranes changed as a function of the concentration of H2SO4 coagulant. RC membranes coagulated with relatively dilute H2SO4 solution exhibited better mechanical properties. Thus, this work provided a promising way to prepare cellulose membranes with different pore sizes and good physical properties.
